Gyro Wheel


Hi
Friends, None of you have learnt the bicycle without facing the wounds. But this generation has the opportunity to enjoy the same but without the wounds. This is possible by only the GYRO Bike which has the self balancing capacity and based upon the  Gyroscopic Principle.

Training wheels are a thing of the past thanks to the revolutionary Gyrowheel. Gyrowheel not only keeps the bike from falling over, it also teaches correct riding technique. Gyrowheel senses unbalanced biking and re-centers the bike under the rider’s weight when the bike starts to wobble. Training wheels can’t do that!
Basic Thing
The magic is in the wheel! Okay, it’s not magic inside is a disk that spins independently of Gyro wheel. When the disk is turned on it creates a force the fancy term is “gyroscopic precession” that stabilizes the bike. Gyrowheel provides high stability at very low speed, making learning to ride easier, safer and a whole lot more fun!

WHAT IS PRECESSION AND WHY DOES GYROWHEEL WORK?
Gyrowheel essentially has a gyroscope inside. Gyroscopes are spinning wheels that exhibit a special property called precession. When a force is put at the top of a spinning wheel (such as a rider falling on a bicycle), rather than falling, the gyroscope simply turns, or precesses, in the direction of the fall. This occurs on normal bike wheels when the bike is traveling at higher speeds. Hence, it is easier to ride a bicycle once you "get going." Gyrowheel takes advantage of this property even when the bike is moving slowly. The disk inside Gyrowheel spins independently of the bike wheel. Thus, even when a rider is moving very slowly on the bicycle, the precession of Gyrowheel is still felt. If the rider begins to fall, Gyrowheel precesses under the rider's weight, restabilizing the bike.

Out of the Vortex

Many of us vexed with the conventional turbines which rotates to produce electricity. From my schooling whatever may be the type of generating power there is a rotation of turbine. And I begin to think is there any case to generate power with out the use of turbine and here is the case:

"Fluids passing over objects can set up vortices with potentially disastrous consequences.Technology can capture energy form the turbulent and convert it into clean, cheap electricity"


               When water flows over any structure vortex is created behind the object and it will have a lot of potentiallity. Because of the disruptive power of the vortex induces vibrations named to be vortex induced vibration (VIV), Engineers have long been interested in trying to spoil vortex shedding and suppress VIV to prevent damge to equipment and strucures. And it's amzing that almost no one has tried to tap their power.

Multi Body Dynamics

Multiple interconnected rigid bodies, is termed to be as Multi Body system.And dynamics concerned to the multibody systems is referred to as the "Multi Body Dynamics"

Exergy

According to first law of thermodynamics energy is neither be created nor be destroyed.In the other words it neither appears nor disappears then how can one produce, Save, Conserve the energy. It is clear, but we have to conserve some thing what is it. There comes the term EXERGY.

We have to conserve Exergy but not Energy.

The exergy of a system is the maximum possible work during a process that brings the system into equilibrium. The term Exergy comes into the picture only when there is a potential difference existence between the system and surroundings, but where as energy always exists in the system.

Energy of a system is always constant but where as Exergy always decreases when the system is tending towards the equilibrium.

Energy never talks about the thermal friction but exergy always quantifies the thermal friction and gives a path to the energy engineers to decrease the thermal friction so that the Efficency of the system can be improved.


“The Exergy century has begun. Fight against the thermal friction.”

What is HyperWorks?

A Platform for Innovation

Altair Engineering’s HyperWorks is a computer-aided engineering (CAE) simulation software platform that allows businesses to create superior, market-leading products efficiently and cost effectively. HyperWorks accomplishes this in two significant ways:

* A flexible software licensing model that replaces expensive traditional licensing plans with a pay-per-use system. Employees across organizational and geographic boundaries will be able to access simultaneously not only the HyperWorks suite, but also a broad range of complementary third-party programs and other Altair products at no extra cost.

* Simulation-driven design technologies that enables achievement of performance, timing, and cost targets through rapid, low-cost, virtual exploration that accelerates informed decision making throughout the product life cycle.


HyperWorks Philosophy

HyperWorks provides the most comprehensive, open-architecture CAE solution in the industry, including best-in-class modeling, analysis, visualization and data management solutions for linear, nonlinear, structural optimization, fluid-structure interaction, and multi-body dynamics applications. Committed to an open-systems philosophy, Altair HyperWorks continues to lead the industry with the broadest interoperability to commercial CAD and CAE solutions in the PLM market space.
